[Gems-users] livelock/deadlock after loading opal.

[Liqun Cheng <liqun.cheng@xxxxxxxxx>]

Hi

The splash2 benchmarks can't not finish after I load the opal module. I
have also tried a tiny "Hello world" program, but the problem remains.
I add two magic instructions: one before printf, and one after printf.
Opal and Ruby are loaded at the callback of the first magic
instruction, everything is performed accordingly to the quickstart
page, but the simics still hasn't reached the second magic instruction
after a whole night on a dual-core  Xeon 2.0G box with 4G memory.
So I suspust there is something wrong with opal. 

BTW, everything is fine on simics and simics+ruby, although I did have some warnings at opal0.init(),
pstate_t: warning: control register #0 == "(null)" has simics name "g0".
pstate_t: warning: control register #1 == "(null)" has simics name "g1".
pstate_t: warning: control register #2 == "(null)" has simics name "g2".

Is this the problem?

What's more, the opal continuously reports something like
patch  PC: 0x44c7e0 0x409800
